Description

Method and device for determining parking fees at

  using parking tickets. The present invention relates to a method for determining parking charges using parking tickets with a magnetizable information memory, in which information, preferably coded, which is read for the determination of the charge, is stored in the information memory before the parking tickets are issued, and in which additional information, in particular on discounts granted or the like, are noted after the emission on at least a portion of the parking tickets The present invention further relates to a device for determining parking charges with at least one parking ticket issuing station which has a magnetizable information memory, in which coded preference information is recorded prior to the transmission of a parking ticket, as well as with at least one reading for reading recorded information

  in the parking ticket information memory.

  Processes and devices of the type mentioned at the beginning are commonly used or installed for the short-term rental of parking spaces, for example in covered car parks At the beginning of parking time, before entering the car park, the user removes from a transmitting station equipped with a barrier a parking ticket in the information memory from which the entry time into the car park was first recorded in a magnetically coded form Once the time has passed parking time has elapsed, the parking time is calculated at a checkout or automatic check-in counter from the entry time recorded on the parking ticket and a parking charge is levied based on the elapsed parking time. Once the parking fee is paid, the entry time recorded on the parking ticket is cleared and the time of payment of the tax is also collected. At the exit of the car park, the user must go through an exit control device in which, after the introduction of the parking ticket, the time of payment of the tax is read and compared at the present time. between the current time and the time of payment of the tax does not exceed a predetermined period, the output is released to the user If the predetermined time difference is exceeded, the user is denied and must pay a

supplement to a box.

  It is desirable, in particular for the operators of a car park connected to a supermarket or similar, but also for a company operating a car park which has concluded appropriate contracts with a plurality of shops, to grant a discount to customers of the supermarket or different shops, different discount levels to be possible depending on the amount of purchases made, up to a free parking However, other users must pay the full parking fee so that discounts may be taken into account when parking fees are paid, they must be noted in the form of additional information on the parking tickets presented by the

  be exploited when calculating the tax.

  Other additional information that can be arranged on the parking ticket at

  distance in time and space of the emission of that-

  This can include, among other things, an access code which allows, for example, customers of a self-service furniture store to access a parking area near the delivery of the goods, whereas this parking remains forbidden to people who park without

  to be customers and to small customers.

  It is already known, in a discount application method, to note the additional information on the parking tickets, for example by punching one or more holes in the parking tickets at the checkouts of a supermarket connected to the parking lot, and grant the delivery of the level corresponding to the holes during the payment of parking fees However, as in this method, the relationship between the perforations and the discount granted is easy to reconstruct for the user, this process is exposed to manipulations in which, for example, the corresponding holes may be provided in the parking ticket using a perforator

  manually to fraudulently receive large discounts.

  In order to prevent such a procedure, the additional information must therefore be noted on the parking ticket so that it can not be

  identified or manipulated by the user.

  This would be the case, for example, optimally if, for each discount or when adding other additional information of this type, the entry time recorded in the parking ticket information memory was read, a free parking period was calculated according to the amount of purchases made and added to the time recorded and that the resulting time was noted on the ticket by erasing the previously recorded time Although the range of possibilities for graduation discounts and similar is very large in such a process, it has the disadvantage that each delivery device, that is to say each box in a supermarket, must contain a device

  read-write for parking tickets.

  The investment for such equipment is, however, so

  high that this system does not find buyers.

  On this basis, the object of the present invention is to improve a method and a device of the type mentioned above so that the additional information can be noted with simple means on the parking ticket, but that they can not be or

  recognized or manipulated by the user.

  This object is achieved according to the present invention, with regard to the method, in that the additional information is recorded next to the input time information already stored in the information memory. The present invention is based on the the idea of ensuring by the introduction of the additional information in the information memory that, on the one hand, the additional information as well as the information recorded before the emission on the parking ticket can not be recognized or manipulated by the on the parking ticket and, on the other hand, that in determining the fee they may be read in the same manner and with the same facilities as the time of entry or with similar facilities. Recording of information additional information in the information memory that is already recorded here means that when one or several discounts are granted separately in time and / or space, one or more marks will be applied separately from the dataset necessary for the subsequent determination of the tax with the coded entry time and independently of it on the parking ticket, so that when determining the tax at the checkout or checkout they can be detected with the same or similar device and taken into account in the calculation of the tax on the basis of time elapsed since entering the car park. An advantageous design of the present invention provides here that all the information recorded on the parking ticket is recorded in the coded form, so that their meaning itself is not easily identifiable, in case the user would obtain fraudulent purposes a device to read

  and modify data stored in this way.

  In the usual parking tickets, on which the information is recorded before transmission on a data track or magnetic strip oriented lengthwise on the parking ticket, the additional information is recorded according to another embodiment. of the present invention on at least one other magnetic track, the magnetic tracks preferably being oriented next to one another and parallel to each other, so that all information can be written or read by passing the parking ticket in front

  at least one read or write head.

  The recording of additional information on the one or more other magnetic tracks is, according to another preferred embodiment of the present invention, in that at least one burst of magnetic flux changes is applied to the other magnetic stripe. not magnetized or pre-magnetized uniformly in the transmitting station (positive marking) A single flux change is theoretically sufficient to record a yes / no information, for example on the agreement of a rebate However, a single change of flux can not always be clearly identified in practice, and the error frequency can therefore be significantly reduced if, as proposed by the present invention, a packet of

  Flow changes (burst) is applied each time.

  Another solution according to another preferred embodiment of the present invention provides also to write before the issue of the parking ticket in the sector of the information memory on which additional information must possibly be recorded later, the recording the additional information in this case by deleting part of the existing data set (negative marking) It is then appropriate that the corresponding sector, ie the other magnetic track provided for the recording of additional information, either written continuously with flow changes and then, when recording additional information, deleting some of the flow changes creates sectors with no change in flow whose number and / or the length reproduce in coded form the additional information Another advantageous embodiment of the The present invention provides here that the writing on the other magnetic track is done with flow changes by writing on it a copy of the data set, which

  contains in coded form the time of entry into the car park.

  By implementing this measure, one can dispense with recording an additional set of data for writing.

  on the other magnetic track in the transmitting station.

  The sector erasure of the fully written magnetic stripe with flow changes for recording additional information in the form of sectors without flux change can be realized in a process of this type electronically by activating an erase head. or, more simply, by means of a buffer with one or more permanent magnets, which is approached to the other magnetic track of the parking ticket when it is in an appropriate position, at a distance such that the changes in flow within a predetermined action sector of the permanent magnet are removed by the identical orientation of all the elementary magnets contained in the sector

  partial matching of magnetic tracks.

  When using the additional information for the application of the discounts, another preferred embodiment of the present invention provides in the two methods described above that the number of discounts granted correlates with the number of bursts of change. in the positive marking or with the number of sectors deleted without a change of flux in the negative marking, preferably equal to or proportional to the latter. The discounts of a different amount can then, for example, be marked by the variation of number of bursts or sectors with no change in flow, ie, for example, the application of a burst or a sector without change of flow results in a discount of 1 DM, whereas for a delivery of 3 DM three valves or sectors without change of flow are marked In a different way, a request for discounts of different amounts can also be satisfied by marking or recording students or

  sectors with no change in flow of different lengths.

  Unlike the first mentioned procedure, it is necessary that when determining the parking tax, not only the number of bursts or sectors without change of flow is counted, but also that their length is taken into account. , which increases the

necessary complexity.

  For the case where a single level of delivery is desired, it is possible in principle, according to another advantageous embodiment of the present invention, to introduce this level of delivery in the form of a marking on the magnetic strip on which the time of entry is recorded before the issuance The contribution of the delivery marking is then done appropriately by erasing the zero bits of synchronization For this purpose, 12 bits zero are arranged at the beginning and at the end of a magnetic track as soon as the encoding, therefore in the transmitting station, for synchronization. At least one of these zero bits can be erased to produce a discount mark.

  high accuracy of reading and writing devices.

  With regard to the device mentioned at the beginning, the object of the present invention is achieved by the fact that it has at least one marking device for recording additional information, in particular on discounts granted or the like , with which the magnetization can be modified in a partial sector of the information memory, so that in addition to the already recorded information it is possible to record separate additional information in

time and / or space.

  A preferred embodiment of the present invention then provides that the parking tickets have a first magnetic track, on which the time of entry is coded in the transmitting station, and at least one other track. magnetic field on which the additional information can be recorded without influencing the recorded entry time. A first advantageous design of the present invention then provides for three magnetic tracks to be provided, the first magnetic track extending along a median axis of the parking ticket and being symmetrically designed in mirror with respect to the median axis. , and the two other magnetic tracks being disposed on both sides of the first magnetic strip parallel thereto and symmetrically mirror-image with respect to the median axis Si, in such an arrangement of the magnetic stripes, the bursts or the non-flux changing sectors are also applied to the other two magnetic tracks symmetrically with respect to the median axis, the tuned reset, i.e., the number of bursts or sectors without flux change, and the time of entry can be exploited during an evaluation of the parking ticket for the calculation of the tax itself by a reading device with only two read heads, if the introduction of the parking ticket in the payment automat must be possible in both directions If the introduction of the parking ticket in the payment machines must be possible in the four possible orientations, two double heads are sufficient in

each reading device.

  On the other hand, another preferred embodiment of the present invention provides two magnetic tracks, the first of which is arranged along the median axis of the parking ticket and symmetrically mirrored thereto, and the second is parallel to the other and asymmetrical with respect to the median axis This certainly means that for reading the data recorded on the first magnetic track and the second, that is to say the time of entry and discounts granted, it takes three or six read heads if the parking ticket must be able to be introduced in the payment machines in two of the

  directions or four directions conceivable.

  However, because of the multiplicity of parking tickets issued, the economy obtained by a small number of reading heads is not as great as it would be.

  with a smaller number of magnetic tracks.

  In a method in which the tuned shifts are applied to the other magnetic track in the form of flow change bursts, another advantageous embodiment of the present invention provides that the marking device has at least one writing head. On the other hand, the marking device may, in a method where the tuned reset is determined by the number of sectors without change of flux on the other magnetic track completely covered by flux changes, have either a head erasing device connected to an erase generator, ie a permanent magnet, movably supported in front of a parking ticket passed through the marking device To determine the position of a parking ticket passed through the device marking device, it is appropriate for the marking device to have a position recognition device coupled to a sensor, which can operate in an electronic mode, optoelectronic and / or electromechanical and which is activated for example by the fact that the parking ticket interrupts the passage of rays between a light source

and a photocell.

  In the case where several discounts must be possible, it is advantageous to provide a sensor that detects bursts or sectors without change of flux already applied to the other magnetic track and positions the parking ticket according to the position of these bursts or sectors without change of flow in positions

  different for marking in the marking device.

  The marking device further suitably has a control unit which can receive an input signal, so that the write or read head or the permanent magnet can be activated by

  according to a desired discount or discount amount.

  Another advantageous embodiment of the present invention provides that the reading device disposed, for example, in an automatic pay station has, according to the number of magnetic tracks on a parking ticket one, two or three read heads, coupled to a calculation unit by which the parking fee is determined, so that it can then be indicated on a display The voltage signals induced in the reading heads during the passage of the parking ticket thereon are amplified at the By means of an amplifier and brought to a level detector which detects flow changes A releasable monostable flip-flop enables the flow changes to be distinguished from the flux change stops and thus to determine the number of bursts of flow changes on the flow detector. unmagnetized magnetic track or pre-magnetized uniformly, or the number of sectors without flux change on the mag track Netique

  fully written with flow changes.

  The present invention is explained below with the aid of several exemplary embodiments shown diagrammatically in the figures. These represent: FIG. 1: a schematic representation of a device for determining parking fees, FIG. 2: a ticket parking with two magnetic tracks, figure 3: a parking ticket with three magnetic tracks, figure 4 a parking ticket with a magnetic strip, figure 5: a schematic representation of a transmitting station, figure 6: a diagram of connection of a marking device, there is shown in FIG. 7: a connection diagram of a reading device, FIGS. 8 a and 8 b: parking tickets with magnetic tracks arranged differently, and a layout of the writing heads in a transmission station corresponding to each one, FIGS. 9a and 9b: the same parking tickets as in FIGS. 8a and 8b and a corresponding provision of the writing and reading heads in a marking device and FIGS. 1a to 1cc: the parking tickets of FIGS. 8 and 9 and a corresponding provision of FIGS.

  reading heads in an automatic cash register.

  The device for the determination of parking charges represented by the figures essentially consists of a transmitting station 2 arranged at the entrance of a car park not shown, to which a user removes a parking ticket 4 before entering the parking lot, several marking devices 8 integrated in the cash registers 6 of a supermarket connected to the parking lot, in which the parking tickets 4 are provided, when the amount of purchases exceeds a fixed sum, one or several discount marks 10 which are read on the parking ticket 4 in an automatic pay station 12 at the same time as the entry time recorded thereon and which serve together for the calculation of the parking fees, as well as a 14 control device disposed at an exit of the parking lot, which allows the exit of the car park when the payment of parking fees has been made in the

rules.

  In the issuing station 2 provided with a barrier 16, the parking tickets 4 connected to each other in the longitudinal direction are removed from a reserve roll 18 or from another reserve, for example a carton with endless tickets, at the request of a user, and brought by one or more return rollers 20 to an exit slot 22, o a parking ticket 4 can be removed at the entrance of each vehicle Before the emission of the parking ticket 4, information is applied to a magnetic track 24 of the parking ticket 4, for example an identification of the car park, an identification of the card and the arrival time at the transmitting station 2. The sending station 2 has for this purpose a write head 28 (W = writer), which is activated by means of a flux change generator 30. is controlled by sig A knife 32 disposed within the device separates the parking ticket 4 from a microcomputer which reads the time indicated by a clock 26 and converts it into signals controlling the flow change generator. parking tickets before the encoding operation, after which it is conveyed by means of unrepresented transport devices to the recording head 38 for coding and is encoded therein. After the coding, the coded parking ticket arrives at the slot

  exit 22 where it can be removed.

  The parking tickets 4 shown in FIGS. 2 to 4, made of strong paper, have a substantially rectangular shape, the corners 34 being beveled in order to facilitate the introduction of the parking tickets 4 into an insertion slot 36, 38 of FIG. the automatic pay station 12 or the control apparatus 14 The various parking tickets 4 are interconnected by small paper bridges 42 which project from the front surfaces 40, so as to be easily separated from one another, and have or several magnetic tracks 44, 46, 48 which extend in the longitudinal direction of the parking ticket 4 over its entire length The magnetic tracks 44, 46, 48 consist of a thin strip of uniform width of plastic or paper in which is integrated a magnetizable fine powder with a soft magnetism While in the embodiment shown in FIG. 2, two magnetic tracks are provided 44, 46, the first of which is arranged along a median axis 50 of the parking ticket 4 and mirror-symmetrically thereto and is used to record the coded arrival time, the second magnetic track 46 is provided for the recording of additional information, in this case that of tuned shifts, and it extends asymmetrically with respect to the median axis 50 parallel to the first magnetic strip 44 and adjacent from it, the magnetic tracks 44, 46 can be directly adjacent or, as it is

  represented, present a small gap between them.

  The parking ticket 4 represented by FIG. 3, on the other hand, has three magnetic tracks 44, 46, 48, whose central track 44 is used to record the arrival time, while discounts granted are recorded on both. other magnetic tracks 46, 48 in the form of markings The two other magnetic tracks 46, 48 are then arranged mirror-symmetrically with respect to the median axis 50 of the ticket.

parking 4.

  In contrast to this, the parking ticket represented by FIG. 4 only has a magnetic strip 44 disposed along its median and mirror-symmetrical axis with respect thereto, in the central sector 52 of which the arrival time is recorded in coded form in the sending station 2, while the two marginal sectors 54 arranged between the central sector 52 and each front face 40 of the parking ticket 4

  serve for the application of discount marks 10.

  The marking devices 8 shown in the form of a connection diagram in FIG. 7 and integrated in the cash registers 6 have a channel 56 for the parking ticket provided with a transport device, not shown, in which the parking tickets 4 are when introduced to be provided with a delivery mark Along the channel for the parking ticket 56, one or more electronic, optoelectronic and / or electromagnetic sensors 58 are arranged to determine the position of the parking ticket 4 in the parking ticket 56. A device 60 for determining the position, coupled with the sensors 58, transmits a signal to a control unit 62 as soon as a parking ticket 4 is in a predetermined delivery position. application of the corresponding discount level is then carried out In the case where a single level of discount is possible, the discount is Always carried out when a parking ticket 4 is introduced into the marking device 8 If several discount levels have to be entered, the marking device 8 has a keyboard with a number of keys corresponding to the number of discount levels The chosen discount level entered via one of the keys. However, it is also possible to directly connect, for example by an interface, the marking device 8 to a cash register 6 With the help of a reset level established on a keyboard 64 of the cash register 6 and actuated by pressing a key and using the final amount displayed by the cash register 6, the command 62 of the marking device 8 decides the level of

discount that is used.

  After setting the reset levels, a generator 66 for a write or erase head 68 or 28 acting on the other magnetic track 46 (FIG. 2), the other magnetic tracks 46, 48 (FIG. marginal sectors 54 of the magnetic strip 44 is activated Instead of a marking device 8 integrated in the cash register 6, it is also possible to provide a separate marking device, which is connected for example by an interface 70 with a box electronic recorder 6. The generator 66 may be designed as a burst generator which, upon activation, applies a packet 72 (bursts) of flux changes on the magnetic track 46 which is not magnetized or pre-magnetized uniformly in the transmitting station 2 or on the two magnetic tracks 46, 48 (positive marking), the central magnetic strip 44 with the arrival time recorded is not affected Depending on whether there is a single level of discount or that several levels of discount must be possible, the burst generator may, when applying the reset, write on the other magnetic track 46 or the two other magnetic tracks 46, 48 symmetrically with several bursts or with a single salvo 72 each time, the number of bursts 72 applied on the magnetic strip 46 or on the magnetic tracks 46 or 48 then preferably reproducing

  the number of discount levels granted.

  Instead of a burst generator, the marking device 8 may also have an erasure generator or a permanent magnet which, when the magnetic strip 46 is activated or approached, or the magnetic strips 46, 48 , appropriately erases one or more partial sectors 74 of the magnetic strip 46 or the two magnetic strips 46, 48 completely covered by flux changes in the emission station 2 (negative marking), that is to say that 'it applies one or more sectors without change of flux on it or these

as discount marks 10.

  The negative marking certainly requires, unlike the positive marking, a pre-magnetization of the magnetic track 46 or magnetic tracks 46, 48, which must be applied in the transmitting station 2 on the magnetic track 46 or the magnetic tracks However, since the number of transmitting stations 2 is generally much smaller than the number of marking devices 8, it is possible to install them without excessive investments of the signal heads. Therefore, although the negative method requires a larger number of write heads in the transmitting station 2, the application of discount marks 10 is on the other hand facilitated by the fact that they can be applied purely mechanically and magnetically with

a permanent magnet.

  Whereas, during the positive marking, the errors can be substantially excluded by the fact that the marks 10 are not formed by isolated flux changes but by a whole packet of flow changes (burst) 72, it is possible to get a redundancy in the negative marking

  which has just been described by the fact that breaks, that is,

  say sectors with no flow changes 74, are relatively large compared to average differences between flux changes in fully covered sectors

flow changes.

  The parking tickets 4, whose central magnetic strip 44 contains the arrival time unchanged by the delivery operation and whose other magnetic track 46 or the other magnetic tracks 46, 48 have been marked as described above. up by delivery marks 10 in the form of bursts 72 or sectors without flow changes 74 as described above, are introduced after the end of the parking time in the introduction slot 36 of the automatic pay station 12, after which it calculates the parking fees due The automatic pay station 12 comprises a reading device 78 (Figure 7) which has according to the arrangement of the magnetic tracks 46, 48 on the parking ticket 4 a different number of read heads 80 The read heads 80 for reading the discount marks 10, on which the other magnetic track 46 or the other magnetic tracks 46, 48 of the parking ticket 4 are passed, are coupled. with an amplifier 82 in which a voltage signal induced in the read head 80 during the passage of the parking ticket 4 is amplified and brought to a level detector 84 connected to the output of the amplifier 82, which detects the changes In a retriggerable monostable flip-flop 86 coupled to the level detector 84, the sectors covered by flux changes and the sectors without flux change are distinguished. The signal thus produced is delivered via an interface 88 and can be operated by an unrepresented computer. or another metering device and to be used therein, with the time elapsed since passing to the transmitting station 2, for the

calculation of parking fees.

  The parking fees due are displayed on a display 90 of the automatic pay station, which also includes a coin introduction opening 92, a return path 94, and a device not shown for printing a receipt, which can be removed by an exit slot 98 of the automatic pay station 12 after

  the actuation of a corresponding button 96.

  The automatic pay station 12 also has a not shown writing head, coupled to a clock, in front of which the central magnetic strip 44 of the parking ticket 4 is passed after the payment of the parking fees indicated on the display 90, the coded entry time recorded on this band is then erased and replaced by a new series of data which records the time of payment of parking fees The parking ticket 4 issued by the exit slot 98 of the automatic pay station 12 must be introduced when leaving the car park in the introduction slot 38 of the control device 14, which then controls whether the period elapsed since the time of payment is less than or greater than a predetermined latency time While, if the elapsed time is less than the latency time, the barrier 16 of the control device 14 is open and the passage is released for the user, the latter is refused when the

  latency is exceeded and must pay extra.

  Unlike the embodiment shown in FIG. 1, it is possible to provide, instead of an automatic cash register 12 separate from the control device 14, a cash box disposed at the exit itself, whose barrier 16 opens immediately after payment of the amount of the

calculated tax.

  FIGS. 8 and 10 each represent the arrangement, the number and the activation of the writing, erasing and reading heads in the transmitting station 2, the marking device 8 and in the reading device 78 of FIGS. automatic boxes 12 according to the number and arrangement of the magnetic tracks 44, 46, 48 on the parking ticket 4 and the selected marking process The dotted areas 100 then represent each time the written sectors with changes in flow, then that the white sectors 102 are sectors without flux change While the activated write heads 28 are designated W (W = writer) and the write heads not activated 28 w, the activated erase heads 68 are correspondingly denoted by E (E = eraser) and the unactivated erase heads 68 by e, as well as the read heads 80 by R (R = reader) and the heads

  readings not activated 80 by r The indication L or R above

  above the edge of the parking ticket 4 designates its left or right edge, while the dotted marks 104 which protrude from a wide side face of the parking ticket 4 indicate the position of the magnetic tracks 44, 46 on the active side of the ticket 4, that is to say on the side that can be written, erased or read by a writing head 25, an erase head 68 or a reading head 80 which faces it. FIGS. , 9 a, i Qa and 10b represent in the left column the arrangement of the writing, erasing and reading heads for the positive marking, while the right column

  represents their provision for negative marking.

  Since the parking tickets 4 are always brought to the writing heads 8 of the transmitting station 2 in the manner in which they are wound on the reserve roll 18, that is to say always with the same orientation, only one writing head 28 is required here when the discount marks 10 must later be arranged, as shown in FIG. 8b, in the marginal sector 54 located at the beginning and at the end of the single magnetic strip 44 or, as the represents the figure 8a in the left column, to be applied by positive marking on another magnetic track 46 or on two other magnetic tracks 46, 48 whose original non-magnetized state is not modified in the position of On the other hand, when subsequently applying the discount marks 10 by negative marking on one or two other magnetic tracks 46 or 46 and 48, two or three write heads 28 are required. Like the other magnetic strip 46 or the other magnetic tracks 46, 48 must be entirely covered by flow changes but the type of flow change is not important, it is appropriate in this case to apply also a copy of the data series containing in form encoded the indication of the time of entry into the parking lot on the other magnetic track 46 or the two other magnetic tracks 46, 48, whose sectors without flow change 74 created during a subsequent delivery operation by the erasing one or more partial sectors 102 of the magnetic strip 46, 48 can be clearly distinguished

  and thus read in the reading apparatus 80.

  The appropriate arrangement of the writing or erasing heads 28 or 68 on opposed wide side faces of the parking ticket 4 in principle makes it possible to apply the discount marks 10 regardless of the orientation of the parking ticket 4 when its introduction into the channel for the parking ticket 56 of the marking device 8 It is however rational, for reasons of cost, to arrange the writing or erasing heads only above (or below) the channel for the parking ticket 56 as shown in Figure 9a, although the parking tickets 4 must then always be introduced into the channel for the parking ticket 56 so that their active side is oriented upwards (or to bottom) on the write or erase heads 28 or 68 As seen in FIG. 9a, two write heads 28 are required, one or two other magnetic tracks 46 or 46 and 48 are applied. on the e parking ticket 4, to apply the discount marks 10 in the positive marking (left column), while in the negative marking (right column), it takes two erasure heads However, when the parking tickets 4 used only have another magnetic track 46, one of the two writing heads 28 or

  both erase heads 68 is still inactive.

  In the case where, as shown in Figure 9b, there is provided a single magnetic strip 44, on which the application of the discount marks 10 is achieved by the erasure of two zero synchronization bits 108 recorded on the magnetic stripe. 44 in the transmission station 2 together with the data series containing in coded form the arrival time and arranged in the marginal sector 54, it is possible to provide for the clearing of the zero synchronization bits 108 two erasing heads 68 on opposite sides of the parking ticket 4, one of which is activated each time, which allows to introduce the parking ticket 4 in any orientation in the channel for the parking ticket However, if the parking ticket 4 is always introduced into the channel for the parking ticket 56 so that the active side is always directed towards the head

  erase, a single erase head 68 disposed

  above the channel for the parking ticket 56 is sufficient. In order to facilitate the use of the automatic pay station 12 by the parking user, it is often requested that a processing of the parking ticket 4 can be done regardless of the orientation in which it is introduced into the parking slot. introduction 36 of the automatic pay station 12 To enable this, for the parking ticket 4 provided with a single other magnetic track 46 represented by FIG. 10 a, for the positive marking as well as for the negative marking, six heads must be provided. In contrast, for the parking ticket 4 shown in FIG. 1 Ob with two additional magnetic tracks 46, 48, on which the discount marks 10 are recorded symmetrically with respect to each other. at the center line, only four read heads 80 are needed.

  two opposing heads are each activated in pairs.

  In the exemplary embodiment shown, the entry time recorded in coded form on the central magnetic strip 44 is read with the reading head 80 on the left, while the right one on the right makes it possible to determine whether are discount marks 10 and, if so, how many, that is, whether discount levels are granted and, if

if so, how much.

  In the parking ticket provided with a single magnetic strip 44 shown in FIG. 1C, two read heads are required, one of which is always activated when the parking ticket 4 must be introduced in any orientation in the box. automatic
